Crossout is an action survival game can be played with just one button. You're a god of war in ancient Africa. You circle around in clock-wise when no button pressed, and in counter-clock-wise if pressed. Once you start to move around in the world, it creates a tail beneath you automatically. You need to circle around the enemies and enclose them with the tail. All your foes enclosed by the tail got destroyed.
